Summary	There are two types of first order partial differential equations that arise over and over again in many algorithms for the control and estimation of nonlinear systems. These types are the Hamilton Jacobi Bellman PDEs (HJB PDEs) and Intertwining PDEs (ITW PDEs). Solutions to one or both these PDEs are essential parts of many algorithms for nonlinear control and estimation yet there are few effective methods for their solution when the state dimension is greater than two or three. We propose to develop new, higher order methods for solving such equations. These method will combine power series techniques, Cauchy-Kovalevskaya techniques, patchy techniques, fast sweeping methods and fast marching methods.
